Abstract: 1,233,985. Impact pulverizers; grinding cement; upward current classifiers; centrifugal classifiers. SOC. DES FORGES ET ATELIERS DU CREUSOT. 1 May, 1969 [10 May, 1968], No. 22277/69. Headings B2A; B2H and B2P. [Also in Division F4] A plant Fig. 1, for pulverizing and drying rough quarried products, particularly in the manufacture of cement, using hot gases from a kiln used to process the pulverized materials comprises a stone-breaker, e.g. a hammer mill 3, a centrifugal dynamic separator 9 which supplies granular material to a crusher, e.g. a ball mill 13 and filtering and separating equipment to separate pulverized material contained in a gas flow from the dynamic separator. This flow is produced by a fan 15. Gas is supplied via ducts 17, 21, 19 to the stone-breaker, the dynamic separator and the crusher in parallel, and from the stone-breaker and crusher to the dynamic separator via a duct 22. A single gas flow charged with pulverized materials is fed along a duct from the dynamic separator at 23 to the filtering and separating equipment. This comprises a precipitation tower 24, having a water atomiser, and an electrostatic filter 25. Fine materials are extracted and discharged via a conveyor 26. A fan 29, a duct 30 and a flow regulator 31 permit a variable proportion of the gas flow leaving the electrostatic filter 25 to be recycled to the dynamic separator 9. The temperature of the gas mixture and pulverized material is monitored by a thermal pick up, the signal controlling either an auxiliary heater 16 or the water supply to the mill 3 or the precipitation tower 24. The dynamic separator, Fig. 2, has a rotor 42 with a section 46 serving as a turbo-centrifuge, and a drying column 52 with a slatted grill 55. Material is introduced via a duct 41 and the heaviest components are hurled against the walls. Two gas flows (at 48 and 54) carry material upwards, and out via ducts 56, while the denser and now dry material falls into the duct 53.

Abstract: 1,264,294. Assembling electrical components. BURROUGHS CORP. 26 June, 1970 [9 July, 1969], No. 31084/70. Heading B3A. Apparatus for handling and inserting integrated circuit units 20 into protective containers 22 comprises an upper slideway 36 for a stack of containers, a lower slideway 38 for a stack of circuit units, an anvil 60 overlying the slideway 36, and a reciprocable pusher 42 which inserts the circuit unit into the container. The pusher is advanced by a cam 48 and returned by a spring 55. An arm 94 is secured to the pusher and a rod 90 passes through the arm, the rod being connected to a rocker arm 88, which is fixed to a shaft on which are mounted upper and lower stack weight restrainers 72, 74. The rod 90, in conjunction with a light spring 98, forms a lost motion connection between the pusher 42 and arm 88. This allows for delay in retracting the restrainer 74 until the unit 20 at the insertion station is clear of the adjacent unit during the insertion stroke of the pusher. As the unit is about to enter the container, the rod 90 is actuated to retract the restrainer 74 and move the restrainer 72 into engagement with the container adjacent the insertion station. The previously assembled unit is ejected into a magazine 70 by an abutment 66 on the pusher 42 and as the pusher is withdrawn, the newly assembled unit slides into the ejection station 62, the lost motion connection effecting a delay in the retraction of the restrainer 72 until after the assembled unit has moved down to the ejection station. Switches 102, 104 are mounted on the pusher and switch actuators 106, 108 are yieldingly connected thereto. The actuators move with the pusher and if one or the other is not stopped by a unit 20 or container 22, the corresponding switch is opened thereby stopping the drive motor of the apparatus.

A cover 2 conceals a bell assembly and prevents relative movement between the back plate 1 and the mounting plate 10. The back plate 1 and enclosure 3 are a onepiece moulding of A.B.S. The telephone set 27 is retained by a risen portion 4 and by the upper rim of the enclosure 3. The telephone set 27 (which may have its own bell assembly as well) is connected to the mounting bracket by a cable (not shown) which is mechanically secured to the bell assembly by a grommet or plug retained in a sub-assembly, Figs.6 to 11 (not shown) secured to the main chassis of the bell assembly 5. The mounting plate 10 has an abutment 15 at its base. Its other three sides have flanges 16 parallel to, but spaced from, the main portion. The back plate 1 is turned over at its top and side edges to define a peripheral groove 17 and the back plate 1 is a close sliding fit on the mounting plate 10, the flanges 16 locating in the groove 17. The abutment 15 fits flush with the bottom of the mounting plate 1. The bell assembly 5 is on a base-plate 18, the front of which is pressed into a groove 19 in the enclosure 3 while the rear is pressed into position past a resilient retaining member 20. The back plate 1 has two rectangular holes 21 just below two lugs 14 in the mounting plate 10. The cover 2 has two lugs 22 on its rear edge which engage in the two holes 21. A ridge  23 at the front of the enclosure 3 co-operates with a locking member 24 to retain the cover 2. Disengagement is by deforming the front wall of the enclosure 3 by insertion of a screwdriver in a small opening 25. A second embodiment housing a bell unit has the same mounting plate 10 mounted on a wall 31 Fig. 5, by screws 32.
